Introduction to Advanced Topics
3 2015 ANSYS, Inc. March 2, 2015
Import and data transfer related properties Applicable for imports Most of the settings done through
Basic Geometry Options
and Advanced Geometry Options
Basic Properties Parameters option for importing
parameters defined in CAD package
Parameter Key filters the parameters from CAD that enter Workbench
If not specified, all parameters enter WB
Geometry Properties (1)
4 2015 ANSYS, Inc. March 2, 2015
Basic Properties (cont.) Named Selection
Define in CAD & transfer to WB
Filter under WB
Set to NS (by default) remove it to import all parameters
Activate WB option
Geometry import / named selections
Advanced Properties Select Use Associativity to establish association between CAD
and WB
Import defined CAD properties :
Coordinate Systems,
Work Points, etc.
Smart CAD Update
Changes made in other options get updated in the mode
Geometry Properties (2) Workbench: Tools Options

In workbench project page File/import Import
Uni-directional connectivity Import neutral/native CAD files directly into Design Modeler
CAD Connections : Approach I
Import I
Geometry cell on project page
Import II
In Design Modeler page Multiple imports possible Appends geometries
Import III
6 2015 ANSYS, Inc. March 2, 2015
Export parameters from CAD to Workbench Parameter change in CAD reflects in
Workbench and vice versa
Direct connection in UG NX
Bi-directional connectivity Launch Workbench from CAD System
CAD Connections : Approach II
Bi-directional CAD connectivity
Attach to Active CAD Geometry Imports active CAD geometry in DM Can attach only saved CAD sessions
Bi-directional import from DM

Helps execute a set of operations repeatedly with different input values Useful for analyzing multiple design points
By modifying geometry/topology parameters
Parameters can be either used for : Sketch dimensions, Plane creation inputs, 3D operation values, etc.
Parameters can be linked with each other through expressions Defined in Design Modeler or Workbench
Parameters can be controlled from Workbench No need for Design Modeler to be opened
CAD Connection
CAD Connections & Parameterization
Parameterization
What is it ?
8 2015 ANSYS, Inc. March 2, 2015
Types of Parameters
Changes the dimensions or locations of a given feature Does not necessarily change the total
number of entities in the model
Geometric parameters
Modifying the feature itself by adding or removing geometry Can change total number of entities in the
model
Topological parameters
Parameterized
number of copies
in a pattern
Parameterized

Creating Parameters in Design Modeler
Procedure
Any input prefixed with the symbol can be parameterized Toggle to D to parameterize that particular input
Default Parameter Name Pattern Feature Name.Dimension Reference
Parameter name can be changed
Example:
A dimension reference (H1) for a sketch created on the XYPlane = XYPlane.H1
A dimension reference (FD1) for Extrude1 = Extrude1.FD1
11 2015 ANSYS, Inc. March 2, 2015
Parameter Manager
Accessible from the Toolbar or Tools menu
Design Parameters tab List the existing parameters & assigned values
Parameter/Dimension Assignments tab Contains expressions
relating the original dimension reference to the value set in the Design Parameters tab
This 2 defined parameters become obsolete and can be suppressed (or deleted)
Create the needed expressions & Check to evaluate them
12 2015 ANSYS, Inc. March 2, 2015
Parameter Manager
Parameters created in Design Modeler can be managed in:
Parameter Editor in DM Parameter Set in WB
Expression can be created in the Outline of All Parameters in WB
Multiple Design Points can be created using different values of the parameterized independent variable
Linked together &
Updated in background

Advanced Sweep Options
Sweep Options
Scale Taper or expand the Profile as it is swept along the path of Sweep
Twist Specification No Twist : Helical sweep is not created
Turns : Specify number of turns to complete over the path length
Pitch : Specify length per 1 full turn
4m

Body Operation: Move, Align and Orient Using By Direction option, one can align bodies by using alignment vertices for aligning axes of bodies and orienting bodies with respect to each other.
User needs to select bodies, pair vertices for Source & Destination Move and directions for Source & Destination Align and/or Source & Destination Orient
16 2015 ANSYS, Inc. March 2, 2015
Coordinate File for 3D Curve
A coordinate file must be a simple text file in the following format:
The pound sign (#) indicates a comment Empty lines are ignored Data consists of five fields, all on one line, separated by
spaces and/or tabs:
Group number (integer)
Point number (integer)
X coordinate
Y coordinate
Z coordinate
A data line cannot contain the same Group number and Sequence number as a previous data line.
For a closed curve, the point number of the last line should be 0. In this case, the coordinate fields are ignored.

Managing External Files The WB project file structure provides a directory named
user_files
The WB protects this directory and ensures that it is managed and archived appropriately.
Files from separate applications that are associated with this project can be safely stored in this directory.
CAD data (imported geometry data) should be stored here, especially if you intend to transfer the project to another computer.
When the project is reopened and the CAD data is not saved in user_files WB will prompt you to locate the file:
From the View Menu, select Files.
Right click on the relevant file in the list and select Repair filename.xxx.
Browse to the file in the user_files folder.
The new path will be saved with the project.
